4 | A fmvj18x (and its compatibles) PCMCIA client driver | |
5 | ||
6 | Contributed by Shingo Fujimoto, shingo@flab.fujitsu.co.jp | |

10 | ||
11 | The PCMCIA client code is based on code written by David Hinds. | |
12 | Network code is based on the "FMV-18x driver" by Yutaka TAMIYA | |
13 | but is actually largely Donald Becker's AT1700 driver, which | |
14 | carries the following attribution: | |
